Berlin’s Museum Sunday offers a good opportunity to take a closer look at the architecture of Haus der Kulturen der Welt (HKW). What materials were used during its construction? How is a curved roof like this constructed—and why did it partially collapse in 1980? Emilienne Fernande Bodo, assistent curator for Architectural and Spatial Practices, takes anyone interested on a tour through the history of the house and its politically charged legacy.
